or a writ of right on the proprietary right. But that the arrangement may prevail  rather than perish1 and that a gift which proceeded from the will of the donor may  take effect,2 if the substitute has lawfully put himself in seisin after the death of  the first donee3 and the donor or his heir claims, the substitute will be given an  exception against his action [based upon] the modus of the gift. If the substitute,  being out of seisin, claims, he has no remedy except by a writ specially formulated  of a substitution effected by the modus of the gift, which recites the modus in its  text.4 The writ will be this, that it may be clear:5
Of supposititious birth and when a woman claims to be pregnant though she is not, to the disherison of the true heir.
 We have said above that one is presumed to be the heir since he is born of the wife,6  and that he is heir whom the marriage shows [to be such].7 Since a child sometimes  is substituted by a wife, who pretends to be pregnant when she is not, [sometimes  by a guardian, who substitutes a stranger after the death of the true heir, and  raises him8 as heir to the inheritance, though he is neither son nor heir, to the disherison  of the true heir,] we must therefore consider supposititious births and how fraud  of that kind may be proved in the royal court. Suppose that a wife, in her husband's  lifetime, or after his death, claims to be pregnant when she is not, to the disherison  of the true heir, [or though she is pregnant it seems unlikely that the offspring can  be that of her deceased husband, 9in which case she must be questioned as to the  time she conceived and the time of her husband's death or departure from her.10  11On this matter may be found in the roll of Hilary and Easter terms in the fifth year  of king Henry in the county of Norfolk, [the case] of Peter Constable of Melton and  Muriel the wife of William de Melton.]1213On the complaint of the true heir [and]  by order of the lord king, the sheriff shall cause the woman to appear before him  and before the keepers of the pleas of the crown (or before one whom the lord  king has appointed a judge) and to be examined by responsible matrons, by feeling  her breasts and abdomen, in order to discover the truth. If there is the slightest14  suspicion of fraud she ought to be kept in custody. The form of writ will be this.
Writ for viewing a woman to discover whether or not she is pregnant.
 15The king to the sheriff, greeting. We command you, setting aside all delays and  impediments, to cause to come before you and before the keepers of the pleas of our  crown
